the place itself is great, the location too. It's easy to find from Hua Lamphong. I would book this apartment again, but only for 2 people. There were three of us and the third person used the bunk bed which, according to her, was quite uncomfortable and you could hear everything from the living room.
The price is quite high and comparable to a decent hotel. The quality of the apartment justifies that, however.
All in all, we were happy.
